Series Connection of Resistors Resistors that are connected in series have a total resistance value that is equal to the sum of all the resistance values of the resistors. RTotal = R1 + R2 + R3 = 200Ω + 250Ω + 1.0KΩ = 1.45kΩ Example: R1 = 200Ω R2 = 250Ω R3 = 1.0kΩ R1=200Ω R2=250Ω R3=1.0kΩ R TOTAL = 1.45kΩ The total resistance is always larger than the largest single resistor! I-I. Parallel Connection of Resistors If all the resistors have the same resistance value, the total resistance will be equal to the resistance value of one resistor divided by the number of resistors. R TOTAL = 20k 100k 100k 100k 100k Example: Five equal resistors R = 100k are connected in parallel. The total resistance RTotal = R/5 = 100/5 = 20k 100k If the resistors that are connected in parallel have different values, the following formula must be used: R TOTAL R1 R2 R3 RTOTAL = 1 _______ = The total resistance is always smaller than the smallest single resistor!

Impedance The expression “impedance” is used in the BELIMO literature in the following way: • Input impedance: The input circuit of a control device, based on its circuitry, has a certain electrical resistance. The value of this resistance determines how much current the device will draw from the controller. This value must be taken into consideration when connecting any device to a controller output. Example: “Input impedance 100 kΩ.” This means that the DC resistance between the input (Y or Y1) and common (COM) is 100 kΩ (100,000 ohm). When the signal is 10 VDC, using Ohm’s Law (I=E/R), the current draw on the output of the controller will be (10V/100,000 Ω) = .0001A = .1 mA for each actuator that is connected to the signal. The combined input impedance must be higher than the controller output impedance. • Output impedance: The output of a controller has a limited amount of current capacity to supply to the devices it is controlling. The capacity can be given in one of 2 ways. One way is by stating it as “Maximum output current .2 mA.” The other is by giving its output impedance. The output impedance must always be lower than the combined input impedance of the devices being controlled. Example I: “Output impedance 1000Ω minimum.” This means that the combined input impedance of the devices being controlled must be greater than 1000Ω. Example II: “Maximum output current .2 mA.” Based on a 0 to 10 VDC control signal, the output impedance would be equal to R=E/I or (10V)/(.0002A) = 50kΩ In general, the higher the input impedance, the lower the current draw, therefore less strain on the controller output. The lower the output impedance, the more current available; the more current available, the more devices can be controlled. I-K. Power Consumption (W) / Volt Amperes (VA) When a device is powered with direct current (DC), or alternating current (AC) into a pure resistive load (bulb, heater, etc.), the rated power consumption is watts (W) and is the product of the current (I) and voltage (E), (W = E x I). 170 F20358 / 5 4 3 2 1 -01/04-10M-IG-Subject to change. © Belimo Aircontrols (USA), Inc. Example: 1 _______ Basic Electricity ® When an actuator is powered with alternating current (AC), the actual power consumption in watts (W) inside the actuator will remain the same. However, due to the inductive and capacitive character of the load, a shift between current and voltage occurs (phase shift). This results in an “apparent” power consumption, which is higher than the actual power consumption. The “apparent” power consumption is expressed in volt-amperes (VA), which is the product of AC volts and the current (VA = V x I x efficiency.) The size of a transformer is expressed in volt-amperes (VA) and not in watts (W). The VA rating of a transformer must be at least as large as the combined VA rating of all the actuators connected to the transformer. Example: Actuator AM24 US. Power consumption: 2.5 W. Transformer sizing: 4.5 VA If five (5) AM24 US are connected to one transformer, the VA rating of the transformer must be 5 x 4.5 VA = 22.5 VA, or larger. It is better to use a number of small transformers than one large one. The Belimo products are designed to be powered from Class II transformers for UL applications. These transformers have internal power limitation. A Class II transformer must not provide more than 30 V and no more than 100 VA output. Do not use a Class I transformer and fuse, because it does not constitute a Class II power source! Example I: Three AM24-SR US actuators are powered from the same wire. The wire run is 100 feet. 60 50 45 40 35 30 25 20 Example I 15 VA 15 Example II 10 9 8 7 A D C B E F G a G 12 6 5 G 14 4 Step #3.

I-L . Wire Sizing Using the correct wire size is important when long wire runs are used. Using too small of a wire increases the resistive losses of the run. The result of this may be too low of a voltage at the actuator to operate correctly. The above chart can be used to determine the correct wire size to use for an application.

Multi-Conductor Wire Types • “BELL WIRE” has parallel wires, which may act as an antenna and is therefore sensitive to electrical noise. This type of wire should not be used for control circuits. • “TWISTED PAIR” cancels out most of the electrical noise because the wires alternate their positions. This is the type of wire that is used for most control circuits. • “SHIELDED WIRE” is a twisted pair that is surrounded by a metal foil or wire mesh which acts as a shield and prevents electrical noise from reaching the wires inside. Shielded wires are used for the BELIMO actuators only if the electrical noise is very severe. Normally twisted pairs are sufficient. Remember! The shield must be grounded in one point only! BELL WIRE TWISTED PAIR SHIELDED WIRE GROUND IN ONE POINT ONLY! (CONNECT THE SHIELD TO GROUND) SHIELDED WIRE GROUND ONE END ONLY! AT EACH JOINT, THE SHIELD HAS TO BE GROUNDED. (BUT IN ONE END ONLY!) SHIELDED WIRE GROUND LOOP! THIS IS WRONG! THE SHIELD MUST BE GROUNDED IN ONE END ONLY, OTHERWISE THERE WILL BE A GROUND LOOP. I-N. Ground Loops If a shield is grounded at both ends of a shielded wire, a ground loop is created. Ground loops will defeat the purpose of shielding, and aggravate the electrical noise problem. Ground loops can also be created by using more than one wire for signal common (COM ⊥). The (-) signal common terminals on the controller are usually interconnected. Therefore, a ground loop is formed when two or more signal common terminals of the controller are wired to the same transformer. (See Fig. 11-5 and 11-6, page 175.) Signal common (COM ⊥) is necessary, as a reference, but only one connection should be used. Redundant signal common terminals should not be connected. A ground loop acts as an antenna and will pick up electrical noise. This should be avoided, by using the correct wiring practice. 172 F20358 / 5 4 3 2 1 -01/04-10M-IG-Subject to change. © Belimo Aircontrols (USA), Inc.

Compatibility of Different Power Supplies Power Supply with Half-Wave Rectifier DIODE Half-wave rectifiers offer the advantage of using the same connection for the AC common and DC common. Therefore, the common of different devices using half-wave rectifiers can be interconnected and use the same power source. + DC Voltage 2 24 VAC CAPACITOR COM ⊥ 1 Some devices, typically DDC controllers, have full-wave rectifiers. In this case, always use a separate transformer for the controller. Power Supply with Full-Wave Rectifier + DC Voltage DIODE DIODE DIODE DIODE Full-wave rectifiers provide more current capacity. Their disadvantage is that the AC and DC sides cannot be interconnected. 24 VAC CAPACITOR COM ⊥ Every device which has a full-wave rectifier must be powered from its own separate transformer, if the COM ⊥ wire is connected to the Common of other devices. Note: If a device with a full-wave rectifier is powered from the same transformer as a device with a half-wave rectifier, a short circuit will result if the commons (COM ⊥) are interconnected. The Belimo products use half-wave rectifiers. Therefore, they may be connected to the same transformer as long as all commons (COM ⊥) are connected to the same leg of the transformer. However, anytime actuators are connected to a controller a separate transformer should be used for the controller power supply unless you know that the controller also uses a half-wave rectifier. 173 Special Wiring F20358 / 5 4 3 2 1 -01/04-10M-IG-Subject to change. © Belimo Aircontrols (USA), Inc. SWITCHING Understanding Wiring Diagrams ® II-C. Connection of Actuators 0 to 10 V Control Signals Signal Loss Due to the high input impedance (100kΩ) of the actuators, the current through the signal wire is very low. Therefore, the loss of signal will be negligible, even if with long wire runs. Example: Three actuators are connected via a 330 ft. (100 meters) long pair of 22 Ga. wires. Each wire has a resistance of 5Ω. The current draw from each actuator is (I = E/R) 10/100,000 = 0.1 mA, when the signal is 10 VDC. The current in the wire will be 3 x 0.1 = 0.3 mA. Because 2 wires, the Common and the Source, go to the actuator, the resistance in the wires is 2 x 5Ω = 10Ω. The loss of signal will be (E = R x I) 10 x 0.3 = 3 mV = -.003V.

BELIMO ACTUATOR TRANSFORMER LINE The controller will regulate the output current (signal) to the desired value, regardless of the resistance (up to a specified value) in the wires and the load resistor. The resistance in the wires will only cause the output voltage of the controller to be slightly higher than the input of the actuators. The advantage with a 4 to 20 mA output signal to the actuators is that wire resistance does not cause any error to the control signal, and that electrical interference is rejected.

The resistor should be located at the actuator.

TRANSFORMER #2 LINE Fig III-1 Sinking 4 to 20mA BELIMO ACTUATOR Controller 500 Ω POWER SUPPLY + 24V DC (Typically) The controller has one terminal that supplies a constant DC voltage (often +24V). The input of the actuators (wire #3) are connected to the constant voltage. A 500Ω resistor is connected between wires #1 and #3 on one actuator connected to each output. (One resistor for each output.)

L(–)I N(+) E ALWAYS USE A SEPARATE TRANSFORMER FOR THE CONTROLLER UNLESS YOU KNOW A HALF-WAVE RECTIFIER IS USED! ** Each output requires its own transformer. (If actuators which are connected to different sinking outputs are powered, by mistake, from the same transformer, all the actuators will respond to the average of the output signals. This can be very deceptive, because when one output signal is changed the corresponding actuator will move, giving the false impression that the system works. The problem is that the other actuators will also move, although they belong to other control loops. For example: Instead of operating the heating and cooling valves and dampers in sequence, the valves and dampers will operate at the same time, which is the wrong control sequence.) Special Wiring Because the signal common of the actuators is variable, each output requires a separate transformer. The signal common of actuators connected to different outputs must never be interconnected. (See note ** in the wiring diagram) BELIMO ACTUATOR 1 + From the controllers point of view, all the #3 terminals of the actuators are at a “common” constant +24VDC. The signal common, wire #1, of the actuators will vary with the control signal. *** Only one 500Ω resistor should be used for multiple actuators wired in parallel. Up to four actuators may be wired in parallel to the 500Ω resistor.

In both a 0 to 10 VDC and sourcing 4 to 20 mA application, the signal is regulated at the positive (+) source of the signal. In a sinking application the signal is regulated between the device being controlled and common. For this reason, the term “Output” in a sinking application is sometimes confusing. 2 COM ⊥ HOT ~ III-C.

Explanation: The diode allows the positive (+) signal to pass through it and does not allow a higher level positive signal to back feed to the other controller. Only the highest controller signal is seen by the actuator. There is a .7 VDC voltage loss across the diode. This makes the actual voltage range 2.7 to 10.7 VDC.
